The present invention relates to a pump having an auto air discharge structure. The purpose of the present invention is to provide the pump including an auto air discharge structure for discharging air inside the pump to the outside of the pump by using the pressure of a fluid in driving the pump without using an electric apparatus or manual operation. According to the present invention, the pump comprises: a driving part; at least one impeller rotated by power transmitted from the driving part, and accommodated inside; and a pump case including an inlet and an outlet. Moreover, the pump comprises an air discharging pipe which is a pipe for forming a flow path for discharging residual air inside the pump case by connecting one end to the upper end of the pump case to be connected to the inside of the upper end of the pump case, and whose one end is connected to a discharging flow path to have one end for forming a relatively lower pressure in comparison with the other end by the flow of a fluid circulating inside the discharging flow path extended from the outlet.
